Destructor

Cancels any outstanding Bluetooth socket functions and closes the socket. Note sockets should be closed or shutdown before destructor is called.

Accepts a connection from a remote Bluetooth socket.

The call extracts the first pending connection on a queue of sockets, the queue size being previously specified by Listen(). On successful completion the blank socket is given the handle of the new socket and it may then be used to transfer data. After completion the accept socket may be used to make further connections with new blank sockets (see Open() on how to open a blank socket).

RSocket::Accept(CBluetoothSocket& aBlankSocket)When this request completes, notification is sent to the MBluetoothSocketNotifier object supplied when this CBluetoothSocket was constructed. This is done in the function MBluetoothSocketNotifier::HandleAcceptCompleteL(TInt aErr)

Reserved for future.

Set up notification of baseband events

Elect to be notified whenever one of a user specified selection of baseband events occurs.

The notification takes place in the pure virtual function MBluetoothSocketNotifier::HandleActivateBasebandEventNotifierCompleteL(TInt aErr, TBTBasebandEventNotification& aEventNotification)

The FIRST notification will take place ALMOST INSTANTANEOUSLY and will be A FULL DESCRIPTION (OR SNAPSHOT) OF THE CURRENT STATE OF THE PHYSICAL LINK irrespective of the specified selection of events wanted. This first notification or snapshot has NOTHING to do with a baseband event occurring. Once this snapshot has taken place, all occurrences of the specified events from the instant of the snapshot onwards will be notified until CBluetoothSocket::CancelBasebandEventNotifier() is called.

PhysicalLinkState(TUint32& aState) if only a single full description of the physical link state is required.TBTPhysicalLinkStateNotifier TBTPhysicalLinkStateNotifierCombinations

Allow low power modes.

The power modes are indicated by aLowPowerModes.

Allow the socket to switch roles. RBTPhysicalLinkAdapter::AllowRoleSwitch()

Asynchronous deletion of the CBluetoothSocket object.

Function will cause asynchronous deletion of CBluetoothSocket object. It should be called if associated MBluetoothSocketNotifier needs to delete CBluetoothSocket from any of its callback functions.

Reports the automatic sniff/unsniff requesting status of the socket.

Sets a Bluetooth socket address.

Sets the local address of a socket. When a socket is opened it has no name associated with it, and binding is required so data can be routed to the socket. Bind() should be called before Listen() or Connect().

RSocket::Bind(TSockAddr& aAddr)

Cancels the Accept() operation. RSocket::CancelAccept()

Cancels all outstanding operations.

Calling it will cause all outstanding operations to cancel. Outstanding operations for a socket include: read, write, Ioctl, connect, accept, shutdown and the Baseband event notifier. All of these operations will be completed by this call.

No further baseband events will be notified.

If this function is called when there is no active baseband notifier, it will do nothing.

Calling this operation will cause any outstanding Write() operation to cancel. RSocket::CancelWrite()

Opens a connection to a specific Bluetooth device by its address.

The address represents the address of the remote Bluetooth device. A socket may only have one connect operation outstanding at any one time. Once the connect is completed, the socket is ready to send or receive data. If a socket is unbound - i.e. Bind() has not been called yet - then it will automatically have a local address allocated.

RSocket::Connect(TBTSockAddr& aAddr)When this request completes, notification is sent to the MBluetoothSocketNotifier object supplied when this CBluetoothSocket was constructed. This is done in the function MBluetoothSocketNotifier::HandleConnectCompleteL(TInt aErr)

Connects to a remote Bluetooth device by address with a defined data-out and data-in descriptor.

The address provided specifies the address of the remote Bluetooth host. Data can be sent in connect request packets, which may be provided in the data-out descriptor, or connect responses, which may be collected in the data-in descriptor.

A socket may only have one connect operation outstanding at any one time. Once the connect is completed, the socket is ready to send or receive data. If a socket is unbound - i.e. Bind() has not been called yet - then it will automatically have a local address allocated.

Sets up a socket to listen for incoming connections.

Before calling this procedure a socket should be opened using Open() and be bound to a local address using Bind().

Listen() creates a queue to hold incoming connections which can be married with blank sockets using Accept().

Once a listen queue has been created it will continue to allow peers to connect until it is full, at which point it will reject any incoming connections as specified by protocol behaviour. When a socket is accepted by the client a space is made available in the queue.

RSocket::Listen(TUint qSize)

Reserved for future.

RSocket::Listen(TUint qSize,const TDesC8& aConnectData)

Sets the Service bits in the Class Of Device. If this is successful, the socket will then be set to Listen for incoming connections.

RSocket::Listen(TUint qSize)

Gets the local address of a socket.

The local address is set either by calling Bind() or it is automatically set when Connect() is called. If a socket is created through Accept() then a socket will inherit the port of its parent unless otherwise specified by a protocol's behaviour. RSocket::LocalName(TSockAddr& aAddr)

Sets up automatic sniff/unsniff requesting for the socket.

If Automatic Sniff requesting is being selected, a timer with default delay in seconds before the idle socket will request the link to go into sniff mode. The CBluetoothSocket::Write() method will clear an outstanding sniff requester and start the CAutoSniffDelayTimer active object which will issue another request for sniff mode once it times out.

If Automatic Sniff requesting is being deselected, a previous sniff requester will be cancelled.

Transfers a socket from one socket server session to another.

It creates the socket in the target session, and removes the socket from the source session. The call is made on an uninitialised RSocket object. The socket system name 'Name()' is used to identify the socket to transfer.

If the call fails, the socket that is being transferred remains with the original session. Success or failure can be checked on the originating socket by calling Info(), which returns KErrNone if the transfer failed, and KErrBadHandle if it succeeded.
